Fluid discharge gun



Dec.25, 1951 w. w. TAYLOR FLUID DISCHARGE GUN Filed Jan. 14, 1949INVENTOR. MLTER 1M TAYLOR BY W ATTORNEY Patented Dec. 25, 1951 UNITEDSTATES PATENT OFFICE 2 Claims.

The present invention relates to improvements in a fluid discharge gun,principally intended to be used in connection with cleaning machines forthe discharge of steam or water, usually under high pressure, against anobject to be cleaned such as a motor vehicle body or sub-structure,industrial machinery and the like.

The principal object of the present invention is to provide a gun of thecharacter described that is light in weight, simple in construction.easy to handle, particularly in close quarters, and that may bemanufactured economically.

It is further proposed in the present invention to provide a gun of thecharacter described that has two hand holds, one for the left hand andone for the right hand, one of the hand holds being fixed with respectto the gun and the sec-- nd hand hold being revolvable on the gun.

My invention is particularly directed to the arrangement of the secondhand hold. A gun of the character described is usually provided with adischarge nozzle at the front end and a hose coupling at the rear end,and it is a particular feature of my invention to arrange the secondhand hold in such a manner that it revolves on the gun just forward ofthe hose coupling but has a gripping section disposed rearwardly of thehose coupling so that the hose is connected to the gun between the twohand holds which aids considerably in the maneuverability of the gun.

It is further proposed in the present invention to arrange the handholds in such a manner with respect to the gun that the entire rearportion of the gun is substantially insulated by the hand holds and noserious injury will result from accidental contact with any part of thegun in the rear half thereof.

Further objects and advantages of my invention will appear as thespecification proceeds, and the novel features of my invention will befully defined in the claims attached hereto.

The preferred form of my invention is illustrated in the accompanyingdrawing, in which Figure 1 shows a side view of my fluid discharge un,and

Figure 2, a section taken along line 2-2 of Figure 1.

While I have shown only the preferred form of my invention, I wish tohave it understood that various changes and modifications may be madewithin the scope of the claims attached hereto without departing fromthe spirit of the invention.

Referring to the drawing in detail, my discharge gun comprises in itsprincipal features a length of pipe I having a front coupling 2 for anozzle 3 and a rear coupling 4 for a hose 5, which latter maybeconsidered, for the purpose of the present invention, the discharge hoseof a cleaning machine such as shown and described in the Malsbary et al.Patent 2,345,614 of April 4, 1944.

A hand hold 6 in the form of a sleeve having an inner diameterconsiderably larger than the outer diameter of the pipe is mounted uponthe latter intermediate the ends thereof and is fixed with respect tothepipe by means of suitable braces I welded to the sleeve and the piperespectively. The hand hold is preferably mounted in such a manner as tobeisomewhat closer tothe rear coupling 4 than to the front coupling 2,as shown in the drawing.

A second hand hold 8 is mounted on the pipe I rearwardly of the firsthand hold and comprises a sleeve 9 revolvable on the pipe I and an armI0 projecting sidewise from the sleeve and terminating in a grippingmember I I' disposed rearwardly of the coupling 4. The gripping memberII is here shown as running parallel to the axis of the pipe, and inspaced relation to the latter. The sleeve 9 is preferably of a length soas to fill the space between the hand hold 6 and the coupling 4 and awasher I2 may be introduced between the braces I and the sleeve 9 toinsure freedom of revolving motion for the latter. In this manner thetwo sleeves combine to substantially insulate the entire rear one-halfof the pipe and to protect the hand of the operator from accidentalcontact with the pipe.

The inner diameter of the sleeve may be made slightly larger than theouter diameter of the pipe I to insure freedom of rotary motion even ifthe pipe should expand under the influence of heat.

In the use of the device the operator grasps the hand hold 6 with onehand and the hand hold II with the other hand. The hand hold 6 is usedfor steering and turning the nozzle while both hand holds are used forsupporting the gun. It is of particular importance that the grippingsection of the swivel handle is disposed behind the nozzle 4 whichcarries the weight of the hose 5 so that the weight of the latter may besaid to be well distributed between the two hands of the operator. Itwill be particularly noted that my gun is very simple in construction,easy to handle, light of weight and economic in the manufacture thereof.

Icla'im:

1. In a fluid discharge gun, a. straight length of pipe having a nozzlecoupling at its front end and a hose coupling at its rear end, a handhold mounted upon the pipe intermediate the length thereof and having aforward end located substantially midway of the pipe and a rear endspaced from the rear end of the pipe so as to leave a rear section ofthe pipe unobstructed, the hand hold comprising a sleeve surrounding thepipe and having an inner diameter greatly in excess of the outer pipediameter so as to provide insulating spacebetween the sleeve and thepipe and having spaced braces for anchoring the ends of the sleeve tothe pipe with freedom of access of outside air'to the space between thesleeve and the pipe, and a second hand hold comprising a sleeverevolvable upon the rear pipe'section forvvardly of the hose couplingand a handle projecting from said sleeve sidewise and havi asubstantially straight gripping section disposed rearwardly of thecoupling and extending parallel to the pipe, with the front end of thegripping section located substantially in the transverse plane of thehose coupling.

2. In a fluid discharge gun, a straight length of pipe having a nozzlecoupling at its front end and a hose coupling at its rear end, a handhold :5

mounted upon the pipe intermediate the length thereof and having aforward end located substantially midway of the pipe and a rear endspaced from the rear end of the pipe so as to leave a rear section ofthe pipe unobstructed, the hand hold comprising a sleeve surrounding thepipe and having an inner diameter greatly in excess of the outer pipediameter so as to provide insulating space between the sleeve and thepipe and 4 having spaced braces for anchoring the ends 01' the sleeve tothe pipe with freedom of access of outside air to the space between thesleeve and the pipe, and a second hand hold comprising a sleeverevolvable upon the rear pipe section forwardly of the hose coupling anda handle projecting from said sleeve sidewise and having a substantiallystraight gripping section disposed rearwardly of the coupling andextending parallel to the pipe, with the front end of the grippingsection located substantially in the transverse plane of the hosecoupling, the second sleeve being substantially coextensive with thesaid rear section of the pipe to continue the insulation to the rear endof the pipe.
